455 P.3d 393
Kan.2020Background
- Eight‑month‑old J.S., temporarily living with defendant Christopher Lyman and family, died after being brought to the hospital Sept. 15, 2013; autopsy and treating physicians found subdural hematoma, multilayered retinal hemorrhages, multiple bruises, and perianal lacerations consistent with abusive head trauma/shaking.
- Lyman was convicted by a jury of felony murder (based on child abuse), abuse of a child by shaking, and aggravated battery; sentenced to life plus concurrent terms; acquitted of aggravated sodomy.
- The State introduced photos from July showing Lyman with his hand on J.S.'s face and a pacifier reading “bad seed,” phone/computer searches about shaken baby syndrome, and DNA evidence from sex toys; medical experts testified injuries required significant force and would render an infant unresponsive.
- Defense proposed forensic pathologist Dr. Thomas Young, who used a self‑styled "inferential test;" the district court excluded his testimony under K.S.A. 60‑456(b)/Daubert for lack of peer review, testing, and general acceptance.
- After conviction, prosecutor Chris Biggs disclosed a possible (but highly uncertain) recollection of seeing a family matching the Lymans at a Wal‑Mart two days before the death; the district court found the memory speculative and not material and denied a new trial and any Brady relief.
- Posttrial requests (motion to change judge based on an unsworn spectator letter alleging the judge slept; attempt to introduce medical records under a stipulation after the expert was excluded; cumulative‑error claim) were denied; Kansas Supreme Court affirmed.
Issues
| Issue | Lyman's Argument | State's Argument | Held |
|---|---|---|---|
| Whether district court erred denying new trial based on Biggs’s post‑trial Wal‑Mart affidavit (also Brady claim) | Biggs’s memory could point to an alternate perpetrator/time; nondisclosure was Brady material and prejudicial | Biggs’s account was speculative, uncorroborated, and immaterial given overwhelming medical evidence | No — evidence speculative, not material; no Brady prejudice shown |
| Whether exclusion of Dr. Young's testimony under K.S.A. 60‑456(b)/Daubert was an abuse of discretion | Young was qualified; his opinions should be admitted (and/or sliced to allow non‑inferential conclusions) | Young’s "inferential test" is untested, unpeer‑reviewed, not generally accepted, and inconsistent with evidentiary law | No — court permissibly excluded Young as his methodology was unreliable |
| Admissibility of prior‑act/photo evidence under K.S.A. 60‑455 as modus operandi, intent, or absence of mistake | Photographs and ‘‘bad seed’’ pacifier were unfairly prejudicial and not probative of charged offenses | Photos show a similar method and contradict defense explanations; probative value outweighs prejudice | No error — photos admissible as 60‑455 evidence to show modus operandi/intent; probative > prejudicial |
| Motion to change judge for alleged sleeping (judicial misconduct) | Judge allegedly nodded off several times; constitutes structural error | Allegation unsupported (unsworn letter, no contemporaneous objection), insufficient to show prejudice | No — procedurally defective (no affidavit) and record insufficient to show misconduct or prejudice |
| Enforceability of stipulation to admit medical records after expert excluded | Stipulation waived hearsay/foundation for records; exclusion of Young shouldn’t bar the records | Stipulation covered records used by testifying experts; without Young there was no proponent under the stipulation | No abuse of discretion — stipulation tied to expert testimony; exclusion justified |
| Whether cumulative errors require reversal | Combined effect of expert exclusion, prior‑acts evidence, judge sleeping, and denial of new trial deprived fair trial | There are no multiple reversible errors to accumulate; evidence against Lyman was strong | No — no reversible errors to accumulate; conviction affirmed |
